3-tab shingles
3-tab is lighter and cheaper upfront. Wind uplift along open lots in Hollis and Canterbury can shorten their life if not nailed to spec.
They are fine on detached sheds or tight budgets — if the scope still lists underlayment and ice protection.
Architectural laminates
Heavier profile, better shadow line, typically higher wind ratings. Pairs well with ridge venting on longer rafter runs.
Manufacturer tiers differ — we put the shingle line and warranty terms in writing on every proposal.
